I have searched a bit and it looks that new JLink costs about 250EUR
that if far too much for me for one-time-use.  But  I have searched a
bit and found something like below - I would be grateful for more
details (especially JLink/JLink2 differences):

I could try to work out this kind of cable || sniff/dump some
operations to someone (Spen? Xiao?) for anlysis (the reader/viewer is
free) - this depends on my time || cable availability depending on
needs :-)
Also to avoid doing thousand things at time (that is unfortunately
already happening to me) I would prefer to first try the SWD working
(code), then make FT2232 cable, then RLink cable (I have one), then
other versions/cables, so currently I dont get to other tasks until
those are finished. But there could be a support for parallel work on
other cables (I can't manage all this myself in sensible time) - and
here I can help in dumping transfers at physical layer :-)

Best regards! :-)

There is no J-Link 2. It is ULink2.

I think this might be an illegal clone version of Keil ULink2.
http://www.keil.com/ulink2/

I think it is not supported by OpenOCD and will only work
under Keil's uVision IDE.

I think this is an illegal clone version of Segger J-Link which could be
found at about US$20 in some part of the world. After all the hardware
cost is low. The value is in the firmware/software/support.

Original Sam-ICE is Atmel OEM version of Segger J-Link. If you
use IAR EWARM, it is locked to Atmel's MCU only. I have no
idea whether this is an official one or a clone.

It looks like an original one. Segger makes them for Atmel, they are 
cheaper because they are restricted to one manufacturer.
It would be interesting to see if OpenOCD could make it work with 
something else.

OpenOCD should be able to make it work with chips from other vendors.
In fact, I've got a demo board from ADI which comes with the ADI's J-Link
(called mIDAS-Link, V7) and I have no problems to get it work under
OpenOCD with other chips from Luminary and NXP. It seems to be
a bit slower though.

I just tried out  V6 Atmel SAM-ICE (Atmel's J-Link version) and it
works fine with the latest git version of OpenOCD to flash a
Luminary LM3S1968. So OpenOCD does make this limitation
of the OEM versions of J-Link gone.
